User Edit of ListPicker

Question

Hello, what i am trying to achieve is to have a user select options from a listpicker list, once they hit save it saves it using isolated storage, then another page loads and displays the saved data.... all that is working fine, now what i want is to have an edit button on the display page and when they tap the edit button it brings them back to the page where the listpick is on and i need the previously selected items in the listpicker to remain selected

is this possible?
